Direct C–H Arylation

CHIMIA, 2022
Bonds between hydrogen and carbon atoms are the most frequent type of bonds in organic molecules. The ability to replace hydrogen atoms by making other types of bonds to carbon atoms can enable simpler access to complex organic molecules by substituting

Copper-catalyzed asymmetric C(sp2)–H arylation for the synthesis of P- and axially chiral phosphorus compounds

Nature Communications, 2023
Transition metal-catalyzed C–H bond functionalization is an important method in organic synthesis, but the development of methods that are lower cost and have a less environmental impact is desirable. Here, a Cu-catalyzed asymmetric C(sp2)–H arylation is

para-Selective C-H amidation of simple arenes with nitriles [PDF]

, 2015
A para-selective C-H amidation of simple arenes with nitriles has been developed. By increasing the amount of arenes, a further meta-selective C-H arylation of the produced amides occurred.

Palladium-Catalyzed C–H Arylation of 1,2,3-Triazoles

Molecules, 2016
Palladium(II) acetate, in combination with triphenylphosphine, catalyzes direct arylation of 1,4-disubstituted 1,2,3-triazoles effectively. This C–H arylation reaction provides facile access to fully substituted triazoles with well-defined regiochemistry.

Selective C(sp3)–H arylation/alkylation of alkanes enabled by paired electrocatalysis

Nature Communications, 2023
We report a combination of electrocatalysis and photoredox catalysis to perform selective C(sp3)–H arylation/alkylation of alkanes, in which a binary catalytic system based on earth-abundant iron and nickel is applied.
